“Hemorrhagic strokes, which account for 13 percent of strokes, are characterized by bleeding from a blood vessel that supplies the brain. The researchers reviewed admission data from hospitals in and around Kaohsiung, Taiwan, an industrial area known for its high levels of air pollution.”

“They found that people with eczema were exposed to higher levels of PM2.5 than those without eczema. People with eczema lived in areas with about 2% higher PM2.5 concentrations, and the risk of eczema increased considerably with higher pollution levels.”

“Ozone air pollution was associated with a significant increase in emphysema. Lung scans of more than 7,000 participants were compared across 6 metropolitan regions in the US and air pollution levels were measured at the homes of study participants.”

“Exposure to air pollutants is associated with poor health outcomes and an increased risk for both acute and chronic diseases. A recent study suggests that air pollution negates some, but not all, of the beneficial effects of vigorous-intensity aerobic exercise.”

“Surprisingly, the concern isn't just that these chemicals affect health but rather the mechanisms by which they do so. A recent study in mice found that exposure to persistent organic pollutants altered the animals' gut microbiome composition, skewing it toward a less beneficial profile.”

“These associations held up even after adjusting for factors such as education, smoking, diabetes, and cardiovascular disease. Although many observational studies are now linking air pollution to dementia it is difficult to establish causation.”

“It is present in fine inhalable particles, with diameters that are generally 2.5 micrograms or less. Exposure to air pollution promotes oxidative stress and increases the risk of developing many chronic diseases, including cardiovascular disease, cancer, hypertension, and diabetes.”

“Sulforaphane promotes the production of glutathione, a powerful antioxidant that facilitates the body's excretion of toxic substances. When glutathione binds with benzene, a known carcinogen present in air pollution, the two form mercapturic acids, which can be excreted and measured in urine.”

“An estimated 4.2 million deaths each year, many of which are cardiovascular disease-related, are associated with exposure to air pollution. The mechanisms that drive this association include systemic inflammation, endothelial dysfunction, oxidative stress, hypertension, and metabolic dysfunction.”

“Watch this clip in which sulforaphane expert Dr. Jed Fahey describes how sulforaphane provides protection from benzene, a carcinogenic compound present in air pollution. Link to study abstract.”
